AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 745 AM EDT WED MAY 16 2007 .SYNOPSIS... A SURFACE LOW ACROSS NEW YORK STATE WILL SLOWLY MOVE NORTHEAST TODAY. A COLD FRONT ACROSS THE OHIO VALLEY...WILL MOVE EAST AND CROSS OUR REGION LATE MORNING INTO THE AFTERNOON. BEHIND THE COLD FRONT...MUCH COOLER AIR WILL FILTER TONIGHT INTO TOMORROW. && .NEAR TERM /UNTIL NOON TODAY/... THUS FAR...KENX RADAR HAS ONLY INDICTED ONCE CLOUD TO GROUND LIGHTNING STRIKE (IN HERKIMER CTY)...DURING THE PAST FEW HOURS. A FIRST LOOK AT THE VSB SAT PIX INDICATES SOME BUILDUPS IN THIS AREA WHILE FURTHER SOUTH AND EAST MOST SENSIBLE CLOUDS HAVE DISSIPATED. THIS MEANS THE AREA FROM THE CD SOUTH AND EASTWARD WILL BE ABLE TO BUILD BACK HEAT. WILL LIKELY HAVE TO RAISE TEMPS ONE TO TWO CATEGORIES IN THIS AREA. WILL TOUCH UP POPS AS WELL TO REFLECT CURRENT TRENDS OF LESS COVERAGE. STILL LOOKING FOR THE COLD FRONT TO REACH KALB BY 18Z...AND KPOU AROUND 21Z. OUR SOUTHERN COUNTIES CONTINUE TO BE OUTLOOKED FOR SVR SPC HAS THIS AREA IN THE SLIGHT RISK CATEGORY FOR BOTH HAIL AND DAMAGING WINDS. LOTS OF ENERGY AVAILABLE...THE KALY SOUNDING LAST NIGHT HAD 2100 JKG OF CAPE...AS WELL AS 1.5 INCHES OF PCPBL WTR. WILL ALSO HAVE TO PAY ATTENTION TO PRECIP AMOUNTS...PARTICULARLY IN OUR NORTHERN ZONES...AS WELL AS MOVEMENT AND POSITIONING OF CELLS. RAIN WILL HAVE WILL HAVE FALLEN ACROSS THIS REGION MUCH OF THE NIGHT...SO THE GROUND WILL BE WET AND LESS RAIN WILL BE NEEDED TO CAUSE FLOODING. && .SHORT TERM /NOON TODAY THROUGH THURSDAY NIGHT/... NCEP AND THE GFS HAVE THE SURFACE LOW CENTERED NEAR KORH THIS EVENING WITH MOST OF THE PRECIP WELL TO THE EAST...AND IT CONTINUES TO MOVE EAST AS AN UPPER TROF WITH A CLOSED 500 HPA LOW DIPS INTO WESTERN PA. THIS WILL BRING ABOUT LOTS OF CLOUDS... COOL TEMPERATURES...AND A CONTINUED CHANCE OF SHOWERS OVER THE REGION. && .LONG TERM /FRIDAY THROUGH TUESDAY/... CLOSED UPPER LOW EVER SO SLOWLY DRIFTS EASTWARD AND BEGINS TO LIFT OUT OF THE REGION SATURDAY AFTERNOON...ALLOWING A MORE ZONAL UPPER FLOW PATTERN TO BECOME ESTABLISHED BY LATE IN THE WEEKEND...RESULTING IN MODERATING TEMPERATURES WITH AFTERNOON TEMPERATURES FRIDAY IN THE 50S AND LOW 60S GRADUALLY INCREASING TO THE UPPER 60S AND LOW 70S BY TUESDAY. A LOW CHANCE OF RAIN CONTINUES THROUGH MOST OF THE WEEKEND WITH DRY WEATHER FOR THE BEGINNING OF NEXT WEEK. && .AVIATION /12Z WEDNESDAY THROUGH SUNDAY/... STARTING OUT LIFR AT KGLF (FOG AND LOW CIGS) WHILE THE OTHER TERMINALS ARE VFR. EXPECT FOG TO SLOWLY DIMINISH AT KGFL AND CIGS TO LIFT ONLY BECAUSE SHOWERS AND POSSIBLY THUNDERSTORMS NEARBY WHICH SHOULD EVENTUALLY MIX THE AIR UP A LITTLE. ELSEWHERE...SHOWERS AND EVENTUALLY SCATTERED THUNDERSTORMS WILL IMPACT TERMINALS LATER THIS MORNING INTO EARLY AFTERNOON WITH MAINLY MVFR THRESHOLD. SPC HAS SLIGHT CHANCE OF SVR IN MAINLY THE KPOU AREA FOR THE OUTSIDE POSSIBILITY OF DAMAGING WINDS AND LARGE HAIL. AT THIS POINT...CONFIDENCE IS WAY TOO LOW TO INCLUDE IN THE TERMINAL BUT BEST TO CHECK FOR FREQUENT UPDATES. THE COLD FRONT WILL SLOWLY CLEAR OUR TERMINALS BETWEEN 16Z AND 21Z. AFTER THAT...WILL BE LEFT WITH LIGHTER SCATTERED SHOWERS AND CEILINGS STRADDLING BETWEEN THE VFR AND MVFR THRESHOLD THROUGH MUCH OF TONIGHT. A GUSTY SOUTHERLY WIND WILL PICK UP LATER THIS MORNING AND TURN NORTHWESTERLY BY TONIGHT. OUTLOOK THU-SUN .THU...VFR CIG VCSH. .FRI...VFR CIG. .SAT...MVFR CIG CHC RA. .SUN...VFR CIG. && .HYDROLOGY...

RIVERS AND STREAMS ROSE SOME OVERNIGHT BUT QUICKLY RECEDED SHORTLY AFTER PCPN ENDED. AN AREA OF LOW PRESSURE AND ITS ASSOCIATED COLD FRONT WILL MOVE ACROSS THE HSA TODAY WITH MOST OF THE PRECIPITATION EXPECTED TO OCCUR BEHIND THE COLD FRONT. QPF AMOUNTS OF 0.50 TO 1 INCH WILL BE COMMON...HIGH PRECIPITABLE WATER VALUES ON THE ORDER OF AN INCH TO AND INCH AND A HALF COUPLED WITH K INDEX VALUES OF 30 TO 35 INDICATE POTENTIAL FOR SOME HIGHER AMOUNTS. LOCALIZED 2 INCH PLUS AMOUNTS POSSIBLE ESPECIALLY WHERE ANY CONVECTIVE CELLS EMBEDDED AND TRAINING OCCURS.
